271500Z POSITION NEAR 20.3N 106.0E. TROPICAL STORM (TS) 05W (MIRINAE), LOCATED APPROXIMATELY 58 NM SOUTH- SOUTHEAST OF HANOI, VIETNAM, HAS TRACKED WEST-NORTHWESTWARD AT 09 KNOTS OVER THE PAST SIX HOURS. RECENT SATELLITE IMAGERY INDICATES THAT TS 05W MADE LANDFALL OVER THE NORTHEAST COAST OF VIETNAM, APPROXIMATELY 60 NM SOUTH-SOUTHEAST OF HANOI, AT 27/12Z. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY SHOWS IMPROVED CONVECTIVE BANDING WRAPPING INTO THE CONSOLIDATED LOW-LEVEL CIRCULATION CENTER (LLCC). CONSEQUENTLY, DVORAK INTENSITY ESTIMATES HAVE INCREASED TO T3.0 (45 KNOTS), WHICH SUPPORTS THE CURRENT INTENSITY ASSESSMENT. RECENT SATCON ESTIMATES OF 50 TO 51 KNOTS ALSO REFLECTS THE RECENT INTENSIFICATION TREND. ADDITIONALLY, SURFACE WINDS FROM BACH LONG VI ISLAND (48839), 97 NM NORTHEAST OF THE CENTER, PEAKED AT 140/48 KNOTS AT 27/09Z AND ARE CURRENTLY AT 140/36 KNOTS. THE CURRENT POSITION IS BASED ON A 271050Z SSMIS 37 GHZ IMAGE, WHICH SHOWS AN ELONGATED MICROWAVE EYE FEATURE POSITIONED ALONG THE NORTHWEST EDGE OF THE AFOREMENTIONED DEEP CONVECTIVE BAND. TS 05W IS FORECAST TO TRACK FURTHER INLAND UNDER THE STEERING INFLUENCE OF THE SUBTROPICAL RIDGE AND WILL DISSIPATE WITHIN THE NEXT 24 HOURS AS IT TRACKS OVER THE MOUNTAINOUS TERRAIN OF VIETNAM. DYNAMIC GUIDANCE IS IN GOOD AGREEMENT, THEREFORE, THERE IS HIGH CONFIDENCE IN THE JTWC FORECAST TRACK. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 271200Z IS 12 FEET.
